PUSH-BUTTON AND CIRCUIT FOR LIGHTING GAS BY ELECTRICITY.

SPECIFICATION forming part of Letters Patent No. 276,285, dated April24, 1883.

(No model.)

To all whom it may concern:

Be it known that I, THOMAS H. RHoDEs, of the city and State of New York,have invented an Improvement in Push-Buttons and Circuits for Lightingand Extinguishing Gas by Electricity, of which the following is aspecification.

In lighting gas by electricity a magnet and spark-points have beenemployed, and a reference is hereby made to Letters Patent No.257,070,granted to me for such meansfor lighting and extinguishing. Inthat apparatus the electric circuit is closed to one magnet for turningon the gas and igniting the same, and to another magnet for shutting offthe gas in extinguishing the light.

My present invention relates to the combination, with the gas lightingand extinguishing apparatus, of a battery, circuitconnections, and acompound push button having two knobs-one white, to be pressed lightingthe gas, the other dark, to be pressed extinguishing the gastwocircuit-closing springs, and one contact-plate. By this means thecircuitconnections are very much simplified and the risk of error inoperating the push-buttons is avoided.

In the drawings, Figure 1 is a diagram representing thecircuit-connections, battery, and electro-magnets. Fig. 2 is an exteriorview of the pushbutton, and Fig. 3 is a vertical section of the same.

The battery B is to be of any desired character. The induction-coil I isin the circuitconnection from one pole of the battery to the gas-pipe orground. The push-button is in the circuit-connection between the batteryand the lighting and extinguishing device. The wire a leads to thecontact-plate b. The two curved springs c and d are connected to thewires cf, that lead to the electro-magnets g h in thelighting andextinguishing apparatus at the burner, the wires from these magnetsbeing connected with the burner to form a ground. The cappiece l of thepush-button covers the springs and contactplate. l t is provided withtwo push-buttons--onc, 0, which is white or light in color, the other,8, which is black or dark. \Vhen the button 0 is pressed the spring 0 isforced against the contact-plate I) and the circuit closed to theelectro-magnet g, which turns on the gas and operates the spark-points.When the dark button 8 is pressed the other electromagnet, h, isenergized, and the gas turned off and the light extinguished.

I claim as my invention- The combination, with a battery, thecircuitconneetions, and the electric gas lighting and extinguishingapparatus, of the compound push-button having a contact-plate connectedto the battery, two circuit-closing springs connected to the wiresleading to the magnets of the gas lighting and extinguishing apparatus,and two push-buttons-one of lightcolor, to be operated when lighting thegas, and the other of dark color, to be operated in extinguishing thegas-substantially as set forth.

Signed by me this 15th day of November, A. D. 1882.

THUS. H. RHODES.
